Fast negative breakdown in thunderstorms
Recent studies have shown that lightning is initiated by a newly-recognized discharge process called fast positive breakdown. Here, the authors present observational evidence of fast breakdown but of negative polarity, seemingly contrary to current ...

Removal of Copper (II) Ions from Polluted Water Using Modified Wheat Bran
The discharge of wastewater containing heavy metals into waterbodies is a major environmental issue that can influence the quality of the water supply; therefore, it is important to remove the pollutants dangerous to living organisms.

Adsorption Optimization of Reactive Red 120 Dye from Aqueous Media using Chitosan-Coated Magnetically Nanoparticles [PDF]
In this study, chitosan-coated magnetically nanoparticles were used to remove the Reactive Red 120 dye from aqueous solution. Chitosan is one of the most famous biological polymers that can be used as adsorbent in the removal of color pollutants ...

Interpreting Charles Lamb’s ‘Neat-Bound Books’
In this paper we consider a much-quoted phrase published by the essayist Charles Lamb (1775–1834) in the London Magazine in 1822 about a desirable quality in books: that they should be ‘strong-backed and neat-bound’. We identify meanings of modifier neat

Electroactive Metal–Organic Frameworks for Electrocatalysis
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.

Atomic oxygen photometric temperature of lightning and its sub-processes with SOPAPILLA
Information on the temperature of lightning sub-processes is crucial to constrain the chemical and energetic impacts of lightning. However, the peer-reviewed literature on even the most energetic of these processes is scant. In this article, we present a
